Vibrations at speed

Put rear up on jack stands, (BLOCK FRONT ETC SAFETY FIRST) and run car in gear, look for any wobbles anywhere, have someone get it up to speed and look and feel for vibrations.

MY assumption is that you have no vibration in neutral at the same RPM the engine would run at 77MPH.

All this MIGHT rule out drive train as issue.

thank you.

I agree Safety first. I like this idea. I am also going to change the driveshaft clocking and take it for a ride. I probably cant lose having a driveline pro do a balance job on the drive shaft.

I would love to take it to a mechanic that I can trust to do a first rate job on ride height and alignment. Both shops in my town assured me they knew how and measured from the lip on the fender.

even one look at the fitment issues I have on my car should tell you not to trust the sheet metal.....
